Benefits of technology

[0017]Advantageously, the present invention provides a more convenient and efficient technique for browsing MIBs. The network administrator no longer has to deal with cryptic NMS terminals to access MIB variables. Further, other embodiments, disclosed in detail below, illustrate how the present invention provides valuable memory saving to network devices.

Problems solved by technology

Management and support issues are perhaps the most difficult issues to grapple with in networked computing.
Unfortunately, administration and support is more costly than for centralized systems.
Networked computing often disperses network devices across a wide geographic area and creates time-consuming problems for network administrators concerned with keeping these systems running.
However, the data stored by the NMS 104 is not as up-to-date as the data in the MIBs.
Unfortunately, there is nothing simple about MIBs or their arcane vocabularies.
MIBs are not very human-friendly as they have been designed to be used by applications.
Moreover, MIBs are typically accessible by humans only through NMS terminals, which are not always convenient for administrators.
The conventional NMS features do not provide human-friendly tools for accessing MIB variables.
In other cases, NMS functions that retrieve and set values of MIB variables are embedded in the NMS software and cannot be used to selectively retrieve values of MIB variables that interest a particular user.

Embodiment Construction

[0027]A method and apparatus for browsing a Management Information Base (MIB) is described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

General Overview

[0028]FIG. 2 shows a high-level view of a network system in which the present invention may be implemented.

[0029]An administrator client 206 communicates with one or more network devices 202 through network 200. The administrator client 206 is any network node, such as an end station device, including a workstation, personal computer, etc. Network 200 is any communication network, or internetwork, including a LAN, WAN, the global...

Abstract

A method and apparatus are disclosed for browsing one or more Management Information Base (MIB) objects that are stored in a network device, such as a router or switch. In one embodiment, the network device receives a connection of a Web browser at an HTTP daemon and further receives a request from the Web browser to obtain the current value of the MIB variable. The request may be sent in a Hypertext Transfer Protocol (HTTP). The HTTP daemon passes the request to an HTTP-SNMP interface. The HTTP-SNMP interface creates an SNMP query for the current value of the MIB variable and sends the query to an SNMP daemon of the network device. The SNMP daemon obtains the current value of the variable from a MIB of the network device. The network device then returns the current value of the MIB variable to the Web browser which can display it.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to managing a computer network. The invention relates more specifically to methods and apparatus for obtaining values of Management Information Base (MIB) variables stored in a network device.BACKGROUND OF THE INVENTION[0002]Computer networks consisting of end stations, routers, hubs, switches, gateways, firewalls, and other network devices are in widespread use. Management and support issues are perhaps the most difficult issues to grapple with in networked computing. The upside is that the benefits of networks are real—lower hardware and software costs, more flexible systems, easier to use front-ends. Unfortunately, administration and support is more costly than for centralized systems. Networked computing often disperses network devices across a wide geographic area and creates time-consuming problems for network administrators concerned with keeping these systems running.[0003]Several conventional standards are ...
